You could also set up views in BIND 9.1.3, which I just did yesterday for the first time. Pretty cool, but took a while since I couldn't find many docs on it. Check out http://sysadmin.oreilly.com/news/views_0501.html for some good info. Also, BIND 9.1.3 supports IPv6, so you will be ready when the time comes ;-) =========== Michael Oliver -----Original Message----- From: Simon J Mudd [mailto:sjmudd@pobox.com] Sent: Friday, December 14, 2001 7:25 AM To: freebsd-questions@freebsd.org Subject: Re: /etc/hosts vs. DNS for local-only machines anthony@freebie.atkielski.com ("Anthony Atkielski") writes: > Anyway, is it better to define local hosts (those on my 10/24 LAN, not > visible from the Net) within DNS, or just within a /etc/hosts file?

Define your own domain "domain.madeup" and make your name server the primary nameserver for this domain. Create the zone file with your hosts and away you go. In /etc/namedb/named.conf zone "domain.makdeup" { type master; file "primaries/db.domain.madeup"; }; This will read a file with the domain information from /etc/namedb/primaries/db.domain.madeup. You need to create this "zone file". db.domain.madeup will have something like the following inside: $TTL 3600 @ IN SOA host.domain.madeup. sjmudd.pobox.com. ( 10 ; serial 10800 ; refresh 3 hours 3600 ; retry after 1 hour 604800 ; expire after 1 week 86400 ) ; minimum ttl NS host.domain.madeup.. IN MX 10 mail.domain.madeup. localhost IN A 127.0.0.1 host IN A 1.2.3.4 mail IN A 2.3.4.5 etc. You'll need to look at a book on zone files to set this up properly, but you should get the idea. If you now change /etc/resolv.conf to include search madeup.domain Then once you start named you should be able to do things like ping mail from host without having to specify anything else. Hope this helps, but do read up on BIND to set things up properly.
